OF LOCOMOTIVES, VEHICLES. OR MACHINERY- Patented Nov. 13, 1906.

Application filed March 31, 1905. Serial No. 253,104.

To all whom it may concern:

Be it known that I, JAMES FRANCIS HER- BERT COLLET, a subject of the King of Great Britain and Ireland, residing at 296 Lordship Lane, Dulwich, in the county of Surrey, England, have invented certain new and useful Apparatus for Recording the Movements of Locomotives, Vehicles, or Machinery, of which the following is a specification.

My invention relates to recording apparatus for indicating the rate of speed, the direction of travel, and the periods of rest of locomotives, motor-cars, tramway or other vehicles, or machinery, my object being to produce a simple and efficient apparatus ca: pable ofrecording in a permanent manner both the duration and the character of the movements made by the locomotive, vehicle, or machine to which the apparatus is applied.

In the accom anying drawings, which illustrate a recor ing apparatus constructed according to m invention, Figure 1 is a face view,Fig. 2 a p an, and Fig. 3 an end view, of the a paratus. Fig. 4, is a vertical section on the line x as in Fig. 1, showing the paper-support and the operating-disk and Fig. 5, a rear viewv of the roller on which the record is wound. Fig. 6 illustrates, to an enlarged scale, the cam for o crating the marker; and Fig. 7, a portion 0 a record indicating the movements of a locomotive.

In apparatus constructed according to my invention I employ an ordinary clock A; but in place of the hands is mounted a disk a, whereof the peri hery is furnished with a series of ins a, a apted to engage in holes b b, forme in the edge of a strip of aper B. This strip of paper is preferably mar ed with a series of transverse arcs represent' g equal intervals of time. As the disk a rotates the strip of paper B, which is supported partly upon the pin-disk a, and part y upon a platform 1), becomes unwound from a roller C, mounted upon the frame of the apparatus, and wound upon a roller D, mounted upon a rocking arm (1, the platform I) serving to support the strip of paper in its passage from the feed-roller to the gathering-roller. The roller D is su ported upon a pin (1, secured to the arm (1', w 'ch in turn is pivotally mounted on the frame of the apparatus at d, a spring d o crating to maintain the roller D in frictiona contact with the edge of the rim a of the disk (1. The disk it rotates the roller D by reason of the frictional contact before referred to, an arm (1 being pivotally mounted on the frame above the roller D in such a manner that its free end rests upon the roller and prevents backlash. A bell-crank springlever E is pivotallymounted upon abracket e at e attached to the frame of the apparatus, and is furnished at its free end with a pricker or striker e for makin the record upon the paper B, the said 'pric er being moved in a direction transverse to the movement of the paper.

For operating the lever E in a horizontal plane a cam e is employed, the latter bearing against an arm e arranged at a right angle to the lever E. For driving the cam 2 a s ur-gear train e e e is employed, the spind e 0 of the pinion a being operated by a worm-wheel e and worm a It is assumed that the worm-wheel shaft eis driven from some working part of the machine, the movements of which are to be recorded. I

For operating the lever E 'n a vertical plane a tappet e is secured upon the front end of the spindle e, the said tap et periodically bearing against the springever E in such a manner as to lift it and then suddenly to release it with a view to causing the pricker orstriker e, carrled at the free end of the resilient lever,.to prick or strike the paper strip B, so as to produce a perforation therein or an impression thereon and then instantly to spring clear of the pa er. These perforations or impressions rnish the desired record of movement, and owing to the traversing action of the lever the pricker or stricker will not strike the paper stri twice in the same spot. A slot 1) is forme in the platform I) in order to permit the pricker to pass through the paper.

The cam 6 which operates the bell-crank lever E, engages the arm e beyond the pivot of the lever, and the cam is so shaped that the lever is gradually moved in the one direction while recording the movements of the machine and then under the influence of the spring e is caused to return quickly in the interval between 'two' consecutive perforations. By operating the lever E in this manher the record holes or impressions are in a series of lines more or less parallel intead of in a zigzag line, as would be the case if the lever moved at an equal speed to and fro across the paper. The cam e is,-moreover, shaped in such a manner as tated in either direction, the hues of perforato admit of its being ro-' IIO ' rocking extremities e tions formed in the paper strip being inclined in the one direction or in the other according to whether the cam e be rotated in one direction or in the other.

The tappet e is preferably provided with with a view to facilitating the sudden release of the spring-lever E in either direction of rotation of the tappet.

The pin-disk a, which drives the paper strip, may be mounted to rotate freely on its spindle like the minute -hand of a clock. Although while driving the paper strip it is in operative connection with the spindle by friction or an adjustable clamp, it can also be rotated independently of the spindle when it is required to set the paper to the actual time of day. In the diagram Fig. 7 the large figure stands for hours and the small figures for minutes.

The interpretation of the diagram is as follows: Assuming the distance between any two of the transverse lines to represent the travel of the paper strip during half a minute and assuming the distance between any two adjacent perforations to represent a previously-fix'ed distance (such as fifty yards) traversed by a locomotive to which the a aratus is applied, it will be seen that short y efore ten oclock the engine started and moved forward about a'quarter of a mile, from f to f. It then immediately reversed and moved backward for about the same distance, f to f Again reversing, it moved forward for about a mile, f to f and then moved backward for about three furlongs, gradually slowing down till it stopped at f The locomotive after Waiting about three minutes started forward again at f going slowly at first and then gradually increasin in speed to f" it traveled at an accelerated speed about sixty miles an hour to f when the speed was quickly reduced to about $170 teen miles an hour.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a paratus for recording the movements and the speed of locomotives, tramway, and other vehicles or of machinery, the combination of a pivotally-mounted bellcrank lever furnished with a pricker at its free extremity, a cam for vibrating said lever in a horizontal plane, a tappet for vibrating the lever in a vertical plane, and means for operating said tappet and cam from the engine or machine the speed or movements of which are to be recorded, substantially as herein described.

2. In apparatus for recording the movements and the speed of locomotives, tramway and other vehicles or of machinery, same being provided with a strip of paper marked to represent certain intervals of time, the combination, with clockwork mechanism, of a pin-wheel engaging said aper strip and driven by said clockwork, a p atform for supporting said paper strip, a marker or pricker arranged above said paper and attached to the free extremity of a pivotallymounted bell-crank lever, a cam for vibrating said lever in a horizontal plane, a ta pet for vibrating said lever in a vertical plane, and means for operating said cam and tappet from the engine, the speed or movements of which are to be recorded, substantially as herein described.
